    older engine drive info

    Cross-posting a bit from the Hobart weld talk forum

    Hi everybody! It's been a while since I posted here. Last time I posted, I was re-doing my Lincoln DC-180. (mixed results, still working on it.... very slowly)

    Now, I have a new-to-me engine drive from Hobart, model GP-258.
    Came with the owners manual, thank goodness. But there's some more info I'm looking for.
    Specifically, the wiring schematic, and what year or range of years was this made?
    Does anyone know where I can find those, especially the wiring schematic?
    Here's what I've got so far:

    Generator: 250A, 40V, 60% duty cycle
    Model GP-258
    Serial 5CW-32354
    Specs 1819
    Type 805819

    Previous owner said it runs and welds, but it does need some work (rough, missing a few parts...)
    And indeed it does run and weld. I intend to use it at my day job (class 8 / heavy equipment mech) and also for side jobs.
    Willys L-134 engine, mostly complete. No idler system, missing air cleaner. I have a K&N filter that will fit.
    Thanks in advance! I hope to document everything here for future reference.
    Use a bigger hammer.

    They have a webpage for literature, but I didn't see anything for that welder. Maybe you can call them to get what you need.

    Here's a schematic for a G-261 that I found (might be similar to yours) -

    Thanks! That is a lot more than I had yesterday.
    The diagram does look like it's pretty similar.
    One thing that has been confusing me is that it seems to have a polarity switch, but in the wrong physical location on the front panel. It also had some kind of insulating strips for the side doors, but I thought the Pipeliner models did not have side doors? So maybe I have a "Mainliner" instead? Will have to get pics sometime, it's at work right now and I'm stuck at home.
